BOOM GOOSENECKS Filed April 17, 1963 United States Patent 3,193,313 BOOM GOOSENECKS Nicholas M. Stiglich, Cresskill, N.J., assignor to George G. Sharp, Inc., New York, N.Y., a corporation of Delaware Filed Apr. 17, 1963, Ser. No. 273,625

2 Claims. (Cl. 287-93) This invention relates to boom goosenecks and more particularly to boom goosenecks for use on cargo or freight vessels.

More particularly still, this invention relates to boom goosenecks for use on cargo or freight vessels which provide support for the foot of the boom and permit full vertical and horizontal movement of the boom together with rotation of the boom about its long axis.

Heretofore, boom goosenecks have been suggested providing the boom with various degrees of rotation in the horizontal and vertical planes but not permitting rotation of the boom about its own long axis. Frequently loads are placed upon the cargo boom of a freight or cargo vessel which tend to twist the boom about its long axis. Furthermore when the booms are elevated at a large angle to the horizontal, the present practice provides a gooseneck which is not sufliciently sensitive to give the boom the necessary freedoms of motion to accommodate lateral translation of the boom head. Unless provision is made for rotation of the boom about its long axis and lateral motion of its head, the boom as Well as the gooseneck may be sprung, broken or otherwise damaged by this excessive strain.

It is therefore an object of the present invention to provide boom goosenecks for supporting the foot of cargo booms of cargo or freight vessels which goosenecks permit maximum freedom of motion and rotation of the boom in three axes in lieu of the usual two, i.e., in horizontal and vertical planes while permitting lateral motion of the head of the boom.

Another object of the present invention is to provide such goosenecks which are relatively cheap to manufacture, while strong and rugged in service and which are easy to lubricate and maintain under the hard usage to which they are put.

Other and further objects of the present invention will appear from the following description of illustrative embodiments thereof.

The boom goosenecks of the present invention are capable of various mechanical embodiments two of which are shown in the accompanying drawings and are described hereinafter to illustrate the invention. These illustrative embodiments should not be construed as defining or limiting the invention.

In the accompanying drawings, in which like reference characters indicate like parts,

FIG. 1 is a schematic drawing of the location on shipboard of the boom goosenecks of the present invention;

FIG. 2 is a perspective view of an illustrative embodiment of the boom goosenecks of the present invention;

FIG. 3 is a front view of the embodiment of FIG. 2;

FIG. 4 is a view as seen from the right in FIG. 3

FIG. 5 is a perspective view of another and preferred embodiment of the present invention;

FIG. 6 is a view as seen from above of the embodiment of FIG. 5;

FIG. 7 is a front view of the embodiment of FIG. 5;

FIG. 8 is a view in section on the line 8-8 of FIG. 7; and

FIG. 9 is a view as seen from the right in FIG. 7.

Referring now to FIG. 1, a mast for a freight or a cargo vessel is generally indicated at 10 and is supported by a deck or other structure 11 forming a base in which the boom gooseneck 12 is mounted. Gooseneck 12 receives the foot of boom 13. Boom 13 is controlled by suitable tackle 14. As seen in this figure, boom 13 can rotate in a horizontal plane through almost 360 but for the area blocked by mast 10 and can rotate in vertical planes through more than 90. As will be apparent hereinafter, boom 13 will have greater freedom to rotate so as to relieve strains placed on the boom during its use.

Referring now to FIGS. 2, 3 and 4, the boom gooseneck 12 of FIG. 1 is seen to comprise a cylindrical spindle 15 which is mounted for rotation in base or structure 11. Spindle 15 is provided with an annular shoulder 16 for engagement with base 11 and shoulder 16 extends upwardly into body portion 17 which may have a semi-cylindrical outer contour. Body 17 is provided with a bearing pocket 18 which is partially cylindrical in shape extending through more than a semi-circle in cross section. Pocket 18 is lined with a suitable bearing metal 19 and receives gudgeon member 28:. Member 20 is shaped to provide a close fit in bearing pocket 18 and has extension 21 through which opening 22 is bored to receive the pin extending between the jaws of boom 13. Gudgeon member 20 is held in bearing pocket 18 by the plate 23 which is suitably secured to body 12 by bolts 24.

It would be apparent that when the jaws of boom 13 are connected to gudgeon member 20 by a bolt passing through opening 22 that boom 13 can rotate in horizontal planes by turning of body 12 and spindle 15 in base 11. Vertical movement of boom 13 takes place around the pin passing through opening 22. Rotation of boom 13 about a horizontal axis is provided by rotation of gudgeon member 20 in bearing pocket 18.

As pointed out above, bearing pocket 18 is greater in cross section than a semi-circle so as to provide shoulders 25 and 26 which engage the adjacent surface of gudgeon member 20 and prevent the same from leaving bearing pocket 18.

Referring now to FIGS. 5-9, another embodiment of the present concept, having the same general characteristics as the embodiment of FIGS. 2-4, is there shown. In this embodiment a cylindrical spindle 27 is provided having lubrication grooves 28 and a screw thread 29 to receive a nut, not shown, for holding the gooseneck in place in its base. This contruction can also be applied to spindle 15. Iin 27 is provided with an annular shoulder 30 resting on base 11 of the gooseneck and shoulder 30 extends into body member 31 which is semi-cylindrical in outer contour. Body 31 is provided with a cylindrical pocket 32 cut away at 33 and having a back wall 34. Gudgeon member 35, having a cylindrical base 36, is mounted for rotation in pocket 32 and has extension 37 provided with aperture 38 therein. Cylindrical base 36 is provided with an axially extending spindle 39 which extends through opening 49 in wall 34 and terminates in threaded portion 41 receiving nut 42 for securing base 36 in pocket 32. Base 36 may be provided with a hearing metal surface 43 which may extend at 44 into opening 40 to facilitate rotation of base 36 in pocket 32. Suitable grease ducts 45 with grease fittings 46 may also be provided.

of the present invention in every way satisfies the several objectives discussed above.

Changes in or modifications to the illustrative embodiments described above may now be suggested to those skilled in the art without departing from the present inventive concept. Reference should therefore be had to the appended claims to determine the scope of this invention.

What is claimed is:

1. A gooseneck comprising a gooseneck body, a cylindrical spindle extending from said body, said body comprising a fiat wall With an aperture therethrough, a semiannular bearing forming flange extending from one side of said Wall, a bearing pocket formed by said flange and said one side of said wall, said pocket opening away from said wall, a gudgeon member comprising a cylindrical portion mounted in said pocket and engaging said flange, a flat surface on the end of said cylindrical portion engaging said one side of said wall, a reduced cylindrical extension on said cylindrical portion extending through said aperture in said flat wall, means on said extension engaging the other side of said wall for holding said cylindrical portion in said pocket, an extensionrfor said gudgeon member extending from said cylindrical portion and normally lying in line with the long axis of said spindle and transverse thereto and an eye in said extension, said semi-annular bearing flange having a cross-- section that increases from each end thereof toward the bottom of said bearing pocket.

2. A gooseneck as described in claim 1, said means for holding said cylindrical portion in said pocket comprising threads on said reduced cylindrical extension and a nut mounted on said thread engaging the other side of said wall.
